This invention relates to a roller nozzle guide for bar mills and moreparticularly to a guide of this character mounted upon the end of theusual pipe or tube, through which bars are customarily passed from thebar mill to the reel or drum, upon which the rolled bars are coiled.

The Objects of the invention are to provide a roller nozzle guide overwhich the bars are passed as they come from the bar mill, to preventscratching or roughening of the under surface of the bars.

The above and other objects may be attained by providing the usual pipeor tube in position to receive the rolled bars as they pass from the barmill, the roller nozzle to which the invention pertains being mountedupon the outer end of the pipe or tube in a position to receive the baras it passes from the tube to the usual reel or drum, upon which therolled bars are coiled- An embodiment of the invention is illustrated inthe accompanying drawing, in which" Figure 1 is a longitudinal,sectional view showing a bar mill, pipe and reel of usual construction,the roller nozzle embodying the invention bein illustrated upon theoutlet end of the pipe;

Fig. 2, an end elevation of the roller nozzle; and

Fig. 3, a section on line 3S, Fig. 2.

Similar numerals of reference indicate corresponding parts throughoutthe drawmg.

Referring to Fig. 1, a bar mill is shown including the housing 1, rolls2, rest bar 3 and guide 4, which may be of any usual construction. Theusual pipe or tube 5 is shown supported in alignment with the guide 4and provided with the tunnel mouth 6, the rod 7 being shown passingthrough the bar mill in the direction of the arrow and entirely throughthe pipe or tube 5, after which it is coiled upon the usual reel or drum8, mounted beyond the pipe.

This much of the construction is in general use where it is commonpractice to coil a rolled bar as it passes from the bar mill and formsno part of the present invention.

It has-been found that in passing a bar from abar mill through a pipe ortube of this kind, and coiling the same upon a reel or drum, the underside of the bar passing over the edge of the pipe, at the point wherethe bar leaves the pipe, is generally scratched or roughened, requiringconsiderable time and labor-to repair the damage to the bar and causingconsiderable waste, as many of the bars are damaged beyond repair.

The present invention has been devised to overcome this diiticulty, andcomprises thenozzle 9, preferably tapered toward its outer end. Thisnozzle may be provided at its inner end with the internal screw threads10 arranged to be mounted upon the threaded extremity 11 of the pipe ortube 5 and has the spaced, depending flanges 12 at its outer end portionbetween which is journaled a grooved roller 13 journaled upon the bolt14, the lower wall of the nozzle being removed between these flanges toreceive the roller- It will be seen that as the bar passes from the barmill, and through the tube or pipe 5 to the reelor drum, the under sideof the bar will be supported upon the grooved roller 13 at the pointwhere the bar leaves the pipe, thus preventing any scratching orroughening of the bar and obviating the necessity of filing or otherwiserepairing the bar, such as is necessary with the present practice ofrolling and coiling bars.

Although the invention is illustrated as applied to the extremity of theusual tube or pipe through which bars are passed to the reel or drumupon which they are coiled,

it will be understood that the invention is applicable to other forms ofbar mills where the bars are not passed through a tube or pipe and afterwhich coiled upon a reel or drum, as the roller nozzle may be supportedin position to receive the bar directly from the guide of the bar mill,the bar being passed through the nozzle and over the roller therein inthe manner above described.

We claim 1. In combination with a bar mill, a pipe arranged to receivethe bars as they pass from the bar mill and a reel upon which the barsare arranged to be coiled as they pass from the pipe, a roller at theextremity of the pipe upon which the bars are arranged to be supportedas they pass to the reel.

2. In combination with a bar mill, a pipe arranged to receive the barsas they pass from the bar mill and a reel upon which the bars arearranged to be coiled as they pass from the pipe, a nozzle mounted uponthe extremity of the pipe and a roller in the nozzle arranged to supportthe bars as they pass to the reel.

3. In combination with a bar mill, a pipearranged to receive the vbarsas they pass from the bar mill and a reel upon which the bars arearranged to be coiled as they pass from the pipe, a tapered nozzlemounted upon the extremity of the pipe and a roller in the nozzlearranged to support the bars as they pass to the reel.

4. A roller nozzle guide of the character described, including a taperedhollow nozzle having a pair of spaced, depending flanges at its taperedend portion, and a roller journaled between said flanges.
